As the new favorite of outdoor advertising, outdoor LED displays have advantages that other advertising carriers do not have, such as visual impact and cost. Due to the high-brightness characteristics of the LED display, even in the daytime, the picture looks very clear and vivid, and has a strong visual impact. If a high-density display is used, this feature is even more obvious, and it will also draw people closer. Viewing distance.
Outdoor LED advertising screen also has the characteristics of 24/7 release. In the past, many companies favored the placement of television advertisements. Although the overall audience for television advertisements was large, the number of television channels was also large, and the prices of good sections and prime time were not low. Relatively speaking, the goal of outdoor LED display is relatively single and concentrated, which can attract the attention of the people around it to the maximum, and the advertisements are scrolled on the big screen every day, repeatedly instilling their advertising content in people, which has strengthened propaganda power.
Outdoor LED display screens have various advantages and are the new darling of the outdoor advertising industry, but also face various problems that need to be improved.
The display screen is mainly composed of four parts in operation, rent, depreciation, electricity and maintenance. The rent and depreciation are almost fixed, and the electricity cost and maintenance mainly depend on the specifications and quality of the display screen. A media company that operates dozens or hundreds of display screens will not have a small monthly electricity bill. Therefore, Energy saving is also an issue that media companies need to pay attention to when purchasing display screens. In addition, maintenance issues are also worth thinking about.
In fact, many media companies now have high requirements for the quality of outdoor LED display screens, because once the display screen is damaged, the media company will suffer considerable losses in both business and maintenance. It is understood that the power supply is a key part that has the most problems in operation. Once the power supply fails, it will directly cause black blocks to appear on the display, which will affect the customer's advertising on the media. Under normal circumstances, there will be a lot of dust and moisture in the outdoor LED display for more than three years and five years, and the main source of power failure is from this. Focus on power protection and damage caused by falling ash and moisture. If the temperature control is not suitable, or the fan has failed for a long time, or the power consumption of the display is large, and the solute is reduced due to long-term high-temperature environment, etc., these are all possible. Damage to the power supply. For these reasons that may damage the power supply, enterprises should also consider how to ensure the normal use of the power supply in various environments.
In addition to the power supply, other fault-prone components are signal lines, control boards, systems, and modules. In the LED display, there are about 500 to 800 signal pins per square meter, so its reliability is also very critical, it determines the quality of the display. Of course, in order to avoid this problem, some companies will use high-standard driver chips and directly cancel the connectors between the modules, but the cost is higher. This part of the control board and system can be said to be the core component. If something goes wrong, it will cause a large area of failure of the display screen, so the stability of the control board and system will have a great impact on the normal use of the display screen. Because the LED display operates outdoors for a long time, high temperature, electromagnetic interference, dust and other factors may cause the control board and system to malfunction. Some manufacturers also have related solutions, such as using dual-line hot backup, but companies can also try Other high-reliability ending solutions provide an extra layer of guarantee for the stable operation of outdoor LED displays. In terms of modules, suitable for various working environments is the pursuit of many media companies. Modules will behave differently in different operating environments. How to reduce its failure rate is also a question worthy of many manufacturers' thinking. All in all, the quality of outdoor LED displays has yet to be improved, which is something that media companies are very concerned about.
Water-proof, heat-dissipating and outdoor lightweight design are still the technical fields that the LED industry needs to break through. The outdoor LED display's use environment determines its waterproof and heat dissipation performance to be more reliable in order to ensure the long-term operation life of outdoor LED media, and cannot rely on the waterproof and heat dissipation design of steel structure. The installation method of hanging, standing or adhering to the building requires that the design of the LED display should take into account the load-bearing requirements of buildings of different building ages, and should be consistent with the building environment or theme.
However, the current LED display industry is based on price, and the focus of market competition is on product prices, thus ignoring the emphasis on quality and after-sales service, causing many serious safety issues and affecting the operating income of media companies. .
'Three highs' is an inevitable development trend in the advertising display industry. With the development of technology, various new things are constantly being updated, as is the LED advertising industry. Especially in terms of display screen interaction and the application of new technologies, because advertising operations are designed to catch the eye and attract more audiences, so as to meet the demand for advertising. However, due to the involvement of advertising displays in the initial stage of construction, the investment costs are quite expensive, and the display has a service life standard. There is still a long way to go before the Three Highs can be realized. In addition, there are also differences in the systems used in the LED display industry, which has also slowed the pace of implementation of the Three Highs. It is suggested that the LED industry unified advertising standards to expedite the elimination of screens with backward technology and long service life, and accelerate the realization of the three highs.
